Stan, I purchased an 18 electric from Sears, on sale $100, regular price $125. Get a sears credit card and get another 5%. It's rated at 4 peak hp. Made by worx. It comes with two chains. I purchased an extended warantee, 3 years, with the 5%.
I have a 3500 watt RV genny. The RV out is raged at 30 amps, 120v, 100 pounds. I put a chain around the genny, connected it to the loader, put chainsaw and oil in bucket of loader and off to the woods I go.
I love it. Genny starts on first or second pull, quiet, no smell. Yes, you have a cord to drag around. My arm doesn't hurt trying to start the saw. I like it so much, I bought a second one, because there was little difference in buying a second one vs buying 2 new chains and a new bar. Didn't buy an extended warantee with second saw. Figure if it goes bad, I'll pitch it and keep the bar and chains.
It cut through an 18 inch red oak log with no problem. Chain may run a little slower, but it seems like it never need to stop and tighten, which can be done with no tools.
Try it, you will like.
